Product Details

The CMP Martyr CMZ03AA is a semi-streamlined aluminum hull anode with an aluminum weld-on strap, engineered for professional-grade cathodic protection on commercial and pleasure craft hulls. Designed to safeguard underwater metal components from galvanic corrosion, this anode is the preferred choice for vessels operating in salt and brackish water environments.

Aluminum anodes outperform zinc in saltwater and are especially superior in brackish water, where zinc can passivate and lose effectiveness entirely. Unlike zinc, aluminum anodes are cadmium-free, making them an environmentally responsible choice. The aluminum strap is welded directly to the hull, creating a reliable electrical bond that ensures maximum protective efficiency throughout the anode's service life.

Key Features:

  • Material: Aluminum alloy anode body with aluminum weld-on strap
  • Dimensions: 12 inch length × 3 inch width × 1.37 inch height
  • Weight: 4.60 lbs
  • Attachment Method: Weld-on; bolt holes can be added to straps as required
  • Ideal For: Salt water and brackish water applications
  • Profile: Semi-streamlined design minimizes hydrodynamic drag on hull surfaces
  • Cadmium-free construction — environmentally compliant

Cross-Reference Part Numbers: ASS-5A, ASS5A, CMASS5A, AZSS-A, AZSS-12A, AZ-3A, AZ3A, ZSS12, HA3A-A

Part of the CMP Martyr commercial hull anode line, the CMZ03AA delivers proven corrosion protection for aluminum hulls, keels, and underwater running gear on workboats, commercial vessels, and larger pleasure craft.
